Stability and Hopf Bifurcation of a Delayed Predator-prey System
摘要/Abstract
摘要:
讨论了具有时滞和基于比率的2种群捕食系统,通过构造合理Lyapunov函数,得到了系统正平衡点全局渐近稳定的充分条件,并讨论了Hopf分支现象。
Abstract:
A two-species ratio-dependent predator-prey system with time delay is investigated.By const ruct ing suitable Ly apunov functional, a set of easily verifiable sufficient conditions are obtained for the global stability of the positive equilibrium of the system, and discussed the Hopf bifurcation.
